Final answer:
Julio is a captive customer of Dr. Amy Page because he keeps visiting her due to the constraints of his health insurance plan, not because he is satisfied with her services.
Step-by-step explanation:
Julio is a repeat customer of Dr. Amy Page because he continues to visit her for health services, despite not being satisfied with her services. He operates under the restrictions of his health insurance network, which provides him healthcare at lower rates, but limits his choice of healthcare provider to those within the network, like Dr. Amy Page. Even though Julio frequently visits Dr. Page due to her being a part of the Pro-Life Inc. network, his reluctance to recommend her services indicates that his loyalty is not based on satisfaction but on circumstance, which defines him as captive rather than loyal. Consequently, for Dr. Amy Page, Julio is a(n) captive customer.
